Main map window in Lightroom Classic CC 7.0 won't refresh

When dragging photos to geotag them in the map module, it will work for a photo or two then nothing visible happens for subsequent photos. The map also does not respond to zooming, panning nor direct input of a place in the location filter/search box. However, the overview map top-left does respond. Further, if a photo is dragged to the main map, it does get geotagged, evidently based on what the main map window should be showing, based on the location shown in the overview.

This bug existed in the previous version as well - very dismayed that it is persisting in 7.0.
